Seeing gravitational waves

When a massive celestial body accelerates its orbit, it will have a huge impact on the curvature of spacetime and manifest as waves propagating at the speed of light. This phenomenon of spacetime disturbance propagation is called gravitational waves. The exhibits simulate the gravitational waves generated by the acceleration and rotation of double black holes through machinery and light and shadow, allowing everyone to "witness" the "ripples" of time and space with their own eyes.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Gravitational waves are one of the predictions of Einstein's theory of general relativity, which refers to vibrations in the bending of spacetime. A mass object will distort the spacetime around it, and the greater the mass of the object, the more severe the distortion of spacetime. In the universe, the acceleration of motion between two massive substances produces spatiotemporal disturbances, and the ripples caused by these disturbances are gravitational waves.
